Abstract: A floor mounted air conditioner comprising a housing containing cylindrical condenser coils disposed about a normally vertical axis and cylindrical evaporator coils coaxially disposed above the condenser coils. A drip pan separates the condenser and evaporator coils and includes openings for discharging condensate onto the condenser coils for evaporation. A condenser fan is associated with a bottom duct adapted for installation in a mounting opening in the floor of a room, for blowing hot air through the mounting opening, and an evaporator fan is associated with a top duct for blowing cool air into the room being cooled.

Abstract: A combination refrigerator has a fresh food compartment and a freezer compartment separated by a partition. To prevent unsightly moisture droplets from forming on the partition surface facing the fresh food compartment, the partition surface is coated with a wetting agent. Any moisture condensation forming spreads out into a thin sheet which minimizes appearance problems. Further, the thin sheet evaporates readily when the door is closed.

Abstract: A refrigerator has a machinery compartment at the bottom for housing a motor-compressor unit and a condenser and has an air inlet opening at the front thereof extending substantially across the width of the compartment. The machinery compartment includes a forward section for receiving the condenser and a duct at the rear portion thereof for receiving the motor-compressor unit. The duct has an air inlet at one end for receiving air from the forward section. The condenser extends generally horizontally from one side wall of the compartment across a substantial portion of the forward section. A drain pan is supported above the condenser for collecting water draining from the interior of the refrigerator. The drain pan additionally functions as a baffle to cause air entering the forward section to flow effectively over the condenser.

Abstract: A coil and cabinet assembly for an air handler is provided in which the refrigerant coil is disposed diagonally within a coil section of the cabinet, the coil having a drain trough for collecting condensate when the air handler is in its upright vertical disposition, a second condensate drain trough adapted for installation in the cabinet at the opposite edge of the coil when the cabinet is to be installed in an inverted upright disposition, both drain troughs having drain outlets projecting from the front face ends of the troughs and extending at their respective locations through lower and upper detachable cross members extending between the opposite sides of the cabinet.

Abstract: An air conditioning structure having a depending centrally located outlet opening and auxiliary air inlets disposed laterally with respect thereto in combination with an air handling mechanism coupled to the outlet and auxiliary air inlets thereof. The air handling mechanism is located within a special support frame for the air conditioning structure, with the frame being adapted to retain and protect insulative material adjacent the exterior surfaces of the air handler mechanism. The air handling mechanism includes a central supply duct for conducting air from the air conditioning structure to a point of use and has a pair of laterally disposed return air handler ducts for conducting and treating the air returned from the point of use to the air conditioning structure, and further includes an exhaust duct extending from the supply duct by which air from the point of use may optionally be exhausted to ambient.

Abstract: An air-conditioning unit with a blower section and an adjacent refrigerant evaporator coil section is adapted to be disposed for airflow through the unit in an upflow, counterflow, or horizontal flow direction by arranging the evaporator coil, and a drip pan separable from both the coil and the coil section, with the drip pan located in any of the four interior corners which extend from front to rear of the unit. The coil has a frame assembly with members at the ends of the fins of the evaporator coil provided with openings for passing condensate into the drain pan, the arrangement being such that either end of the coil may be received within the drain pan. The arrangement also includes the provision of means for supporting the coil from the drain pan in a pivotal engagement to accommodate the difference in angle at which the coil projects from the drain pan in accordance with whether the positioning of the unit is vertical or horizontal.

Abstract: Disclosed is a housing for enclosing the expansion coil assembly and blower fans for an air conditioning system. The housing employs a shield or false floor which defines a cavity below the coil assembly to permit condensed moisture to collect and drain from the housing without becoming entrained in the flow of air through the coil assembly. The shield also includes adjustable tabs for positioning various sizes of coil assemblies on the top surface of the shield.

Abstract: The present invention provides a condensate guide arranged in the path of a flow of air through an A-coil heat exchanger including slabs oriented generally horizontally relative to the air flow. The condensate guide is positioned downstream of the heat exchanger so that condensate when blown from the surface of the heat exchanger by the air flow therethrough impinges on the guide thereby removing it from the path of air and directing it to an appropriate drain.

Abstract: A condensate pan for the evaporator core in a vehicle air conditioning system. The condensate pan is constructed of an insulating material forming a liquid-tight surface on the walls of the condensate pan.

Abstract: An improved insert for a vertical tube condenser comprising a trunk having a plurality of upward extending branches of different lengths formed to have a dense uniform pattern of pick-off points over the tube surface so as to effectively pick-off, by capillary action, the great part of the condensate and to maintain a relatively thin average thickness of condensate on the surface.

Abstract: In a heat pipe the portion of the wicking material which receives the liquid condensed at the condenser surface at the heat output end of the heat pipe is provided with a plurality of large openings extending from the surface adjacent the condenser surface to the opposing surface thereof to avoid condensate accumulation adjacent the condensation surface. Such accumulation blocks access of the condensation surface to vapor and hence increases the thermal impedance of the heat output end of the heat pipe.
